[0031] In one embodiment of the present invention, the cabinet door assembly 2 includes a frame 21 hinged to the freezer body 1, an automatic return assembly 22 disposed inside the vertical side of one side of the frame 21, and a heat preservation and heating assembly 23 disposed inside the frame 21.

[0032] In one embodiment of this utility model, the heat preservation and heating component 23 includes a vacuum glass 231 disposed on the outermost layer and an electric heating glass 232 disposed inside the vacuum glass 231. A sealing frame 234 is provided between the electric heating glass 232 and the vacuum glass 231. One corner of the sealing frame 234 is provided with an input port through which a lead wire can pass. Its output end is connected to the electric heating glass 232. The electric heating glass 232 can be heated by setting a conductive mesh inside the electric heating glass 232 or by attaching a conductive film to the electric heating glass 232. The conductive mesh mainly uses an electric heating wire as a heating element, and the conductive film mainly uses a conductive film as a heating element. After the electric heating glass 232 is energized, the conductive mesh heating element starts to work. The temperature can be freely controlled within a controllable range, which can effectively control the temperature of the window surface in environments with large indoor and outdoor temperature differences.

[0033] In one embodiment of this utility model, the limiting component includes connectors 31 respectively disposed between each side of the sealing frame 234 and the frame 21. Each connector 31 has a limiting groove 32 on its inner side for engaging the heat insulation heating component 23 on all four sides. The width of the limiting groove 32 is adapted to the thickness of the heat insulation heating component 23 to ensure the stability of the heat insulation heating component 23 after it is installed in the frame 21.

[0034] In one embodiment of this utility model, the automatic return component 22 includes a first torsion spring 221 and a second torsion spring 222, one end of which is fixedly connected to the upper and lower ends of the freezer body 1 respectively. Both the first torsion spring 221 and the second torsion spring 222 are made of steel. The other ends of the first torsion spring 221 and the second torsion spring 222 are respectively provided with hook portions, so that the hook portions at one end of the first torsion spring 221 and the second torsion spring 222 are hooked together. After the frame 21 is opened, it does not need to be closed manually. The frame 21 can automatically spring back and close under the action of elastic potential energy.

[0035] In one embodiment of this utility model, the first torsion spring 221 and the second torsion spring 222 are respectively provided with L-shaped limiting members 223. The two ends of the limiting members 223 can be inserted into the corresponding connecting members 31 respectively. Therefore, after the frame 21 is opened, during the process of the frame 21 automatically rebounding and closing under the action of elastic potential energy, the deformation degree of the first torsion spring 221 and the second torsion spring 222 can be effectively controlled, thereby increasing the durability of the automatic return component.

[0036] In one embodiment of this utility model, the storage component includes a plurality of load-bearing plates 41 arranged in parallel along the height direction of the freezer body 1, and two mounting strips 42 on the inner walls of both sides of the freezer body 1 for placing the load-bearing plates 41. The load-bearing plates 41 are hollowed out, and each load-bearing plate 41 has a handle on its outer side. Each mounting strip 42 has a plurality of limiting holes spaced apart to adjust the specific installation position of the load-bearing plates 41 and the distance between adjacent load-bearing plates 41.

[0037] In one embodiment of this utility model, a ventilation fan 6 is provided inside the freezer body 1. The ventilation fan 6 is located at the top of the freezer body 1 and is inclined to prevent direct airflow onto the items on the uppermost load-bearing plate 41.

[0038] In one embodiment of this utility model, the convenient moving component 5 includes brackets 51 respectively arranged at the four corners of the bottom surface of the freezer body 1 and rolling bodies 52 respectively hinged to the brackets 51 at both ends. The rolling bodies 52 are cylinders or spheres, preferably cylinders to increase the contact area between the rolling bodies 52 and the ground, thereby ensuring the stability of the freezer.

[0039] In one embodiment of this utility model, a sealing component is provided between the frame 21 and the freezer body 1. The sealing component includes a sealing strip provided along the outer side of the opening circumference. The sealing strip can maintain the seal and prolong the preservation effect. Its structure consists of a soft polyvinyl chloride jacket and a magnetic strip. The soft polyvinyl chloride jacket is formed by extrusion process, and the magnetic strip is made by mixing magnetic material and plasticizer and then magnetizing it. It achieves sealing by adsorbing onto the outside of the freezer body 1.

[0040] In one embodiment of this utility model, a pressure balancing valve is provided inside the freezer body 1. After the freezer door is opened and closed, the fan turns on the freezer body 1 to form a strong convection airflow, which creates negative pressure inside, making it difficult to open the door for a short time. Therefore, a pressure balancing valve is used. When the door is opened and closed, the convection airflow inside the freezer body 1 blows up the sealing ball and exhausts the air outward to quickly balance the air pressure inside the freezer.

[0041] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
